E. Ramalingam, Raj Mohan B. and M.N. Madhyastha ≈ Biosorption of Heavy Metals from Wastewater by using Aquatic PlantsThis paper describes the use of pollutant-accumulating plants for aquatic pollution abatement, an emerging technology called Phytoremediation. This Biotechnology is overruling Chemical technologies used for cleanup, which are costly, non-ecofriendly and generate more secondary wastes which impair the ecosystem functioning.

Robert K. Rebori ≈ Should Onsite Wastewater Follow Agriculture´s Lead?With farmers finding much success with hardwood chips, the onsite industry could also benefit from looking into alternative denitrification processes for treating high nitrate wastewaters.

Aapo Sääsk ≈ The Arsenic ChallengeSevere health effects have been observed in populations drinking arsenic-rich water over long periods. This paper describes an effective process using membrane distillation (MD) for arsenic removal.

R.D. Schuiling and J.J.P. Zijlstra ≈ Geochemical Engineering: Natural Solutions for Environmental ProblemsGeochemical engineers develop cost-effective methods to remediate pollution in the natural environment. They are inspired by nature and use the knowledge of geochemists about the geochemical cycle and the interaction between minerals and chemical compounds in solution.
